Casilla picked up his 32nd save of the season, striking out two batters in the ninth inning to secure the 7-4 victory over the Rockies

Casilla struck out Ben Paulsen and Justin Morneau to begin the inning and then induced a groundout from Rafael Ynoa to end the game. He's struggled to keep runners off base this season (1.34 WHIP prior to Sunday) yet he's still 32-for-37 in save chances this year and he should continue to get more opportunities for a limited Giants' bullpen.

Casilla picked up his 31st save of the year on Wednesday, striking out two batters in the ninth inning of a 4-2 win over the Cubs.

He struck out Kris Bryant to begin the inning and then induced a Miguel Montero groundout before striking out Dexter Fowler to end the game. It was just the third time in his last 12 outings Casilla did not allow a baserunner, yet he has now converted 11 of his last 12 saves chances.

Casilla recorded his 30th save of the season with a scoreless ninth inning as San Francisco defeated the Pirates 6-4 Friday night.

He has converted 10 of his last 11 save chances, but it hasn't been without incident so allowing just one baserunner (a walk) was encouraging. Over those last 11 appearances Casilla has allowed 19 runners to reach in just 12.1 innings. The Giants just don't have many good options, so he will likely continue to get the call in the ninth if he can avoid any serious disasters.

Casilla earned his 29th save Tuesday against St. Louis with a clean inning. He struck out two.

Casilla has now converted nine of his past 10 save opportunities. Still, he has given up 12 hits and six walks in 11.1 innings over that span, a 1.588 WHIP. Casilla has a 3.70 ERA and is likely to be a cardiac case for his owners as the season winds down.

Casilla picked up his 28th save of the season Thursday against the Nationals, striking out one in a scoreless ninth.

Casilla bounced back from his previous outing -- in which he allowed three runs in 0.1 innings -- to pick up his 28th save in 33 chances. For the season, the Giants' closer has a 3.79 ERA, 1.49 WHIP and 41:18 K:BB ratio.

Casilla imploded in the ninth inning Monday, surrendering two runs while failing to strike out a batter in the extra-innings loss to the Braves.

Casilla was not able to close the door for the fifth time this season, and this was was especially painful as the Giants ended up losing in extras to a sub-500 Braves club. While it was just his fifth blown save in 32 chances, his 3.32 ERA and 1.47 WHIP are numbers you wouldn't expect from a top-tier closer. There are always rumors of a role shift when a closer implodes like Casilla did Monday, but those close to the team have stated that they don't expect Bochy to make a change quite yet. For those who like to speculate for saves, Hunter Strickland (1.86 ERA, 10.24 K/9) and Sergio Romo (80 career saves) would be the likely replacements if Casilla were to lose the closer's gig.

Casilla struck out a pair as he worked around a hit and a walk to record his 26th save of the season Sunday against the Athletics.

It was the 34-year-old's second save in as many nights, and also the second time he put multiple men on base. Casilla continues to play with fire, as his 1.39 ERA will reflect, but he has recorded the seventh-most saves in baseball and has a respectable 2.97 ERA. He appears to have a firm hold on the closer's role at this time and should continue to be a solid source of saves.

Casilla worked around a hit and a walk in a scoreless ninth inning Saturday to notch his 25th save of the season. He struck out one.

While he's certainly not among the elite closers in the league, Casilla has now worked three straight scoreless innings coming out of the All-Star break and still seems to have a firm hold on the Giants' ninth-inning duties.

Casilla picked up his 24th save of the season Sunday, giving up one hit in an inning against the Diamondbacks.

Casilla is having his worst season in San Francisco this year, but has still picked up 24 saves this season, good for sixth in the National League. After a few hiccups earlier in the month, Casilla looks to still be safely holding down the closer's role.

Casilla allowed one run on two hits, but still earned the save in Sunday's 4-2 win over the Phillies.

Despite giving up the run, Casilla has now converted three consecutive saves since his disastrous blown save against the Marlins on July 1. After the implosion, manager Bruce Bochy said he would consider using other options in the ninth, but it appears Casilla has regained his manager's confidence and should be considered the closer going forward.

Casilla picked up his 21st save of the season Tuesday, closing the door on the Mets with a scoreless innings.

Casilla picked up a much-needed save after giving up four runs over his last two outings. It was reported that manager Bruce Bochy would mix and match in the ninth inning given the recent struggles of his closer. Tuesday's clean save should restore some confidence in Casilla, and he figures to see the majority of save opportunities until he falters again.

The Giants will mix and match in the ninth inning in the short term, with Casilla and Sergio Romo both struggling, CSN Bay Area's Alex Pavlovic reports.

It's hard to say what direction the Giants will go, but manager Bruce Bochy will likely play the matchups, as he is adept at doing from many years in the postseason. Casilla, who has given up four runs while recording just one out in his last two appearances, is still worth owning in most formats, but his stock is certainly trending down.

Casilla (general soreness) retired just one of the three batters he faced in Monday's game against the Mets.

He allowed one run on two hits, and struck out one, making his first appearance since July 1 due to an ailment the Giants have labeled as general soreness. With a 3.30 ERA and 1.40 WHIP over 30 innings this season, Casilla may be losing his grip on the closer role in San Francisco. It remains to be seen if the team will seek bullpen reinforcements via trade at the upcoming non-waiver deadline.

Casilla will not be used for a few days according to manager Bruce Bochy, Andrew Baggarly of CSN Bay Area reports.

Casilla gave up three runs without recording an out Wednesday, blowing his first save (and allowing his first runs) since May 31. According to Bochy, his stuff wasn't the same due to general arm fatigue, so the team determined the best course of action will be to rest the closer for an unspecified period of time. With Casilla unavailable, look for Sergio Romo and Javier Lopez to close games based on matchups.

San Francisco Giants closer Santiago Casilla will not be used for a few days because of arm fatigue, according to CSN Bay Area.

San Francisco Giants closer Santiago Casilla will not be used for a few days because of arm fatigue, according to CSN Bay Area. Casilla blew Wednesday's save opportunity, allowing three runs without retiring a batter, and manager Bruce Bochy felt that he looked tired on the mound. “He was really off,” Bochy said. “We played great, did a lot of good things, come back to take the lead, and unfortunately, it’s baseball. The closer was off last night, and that’s the difference in the game. He didn't look like the same Casilla last night. His stuff was down." Casilla has been solid this season on the whole, as he had posted nine consecutive scoreless appearances prior to Wedneesday's meltdown and still has only blown four saves on the season. Casilla should resume his typical role as the team's closer following a few days of rest.

Casilla blew a save against the Marlins on Wednesday, giving up three runs on three hits while recording no outs.

After giving up no runs in nine outings in the month of June, Casilla gave up back-to-back singles then a three-run home run to Justin Bour in his first outing in July. It was the fourth time in 24 chances that Casilla has blown a save this season.

Casilla worked around a hit to record the final two outs of Sunday's game against the Rockies, earning his 21st save of the season.

It was the fifth time this season that the 34-year-old earned a save in less than an inning of work, and he continues to get the job done regardless of the situation. Casilla now owns a 2.12 ERA on the season and is firmly entrenched as the closer for the Giants.

Casilla walked one in a scoreless ninth inning Saturday to notch his 20th save of the season.

He continues to cruise along as the Giants' closer and with Sergio Romo struggling to keep his ERA below 4.00, Casilla's got plenty of job security.

Casilla struck out the only batter he faced to earn his 19th save of the season Friday against the Dodgers.

The Giants had a comfortable lead entering the ninth but a save situation arose after the Dodgers put men on base and scored a run. Enter Casilla, who slammed the door, solidifying his place as the team's go-to option in high-leverage situations at the end of the game.

Casilla walked one and struck out two in a shutout inning Saturday to notch his 17th save of the season.

He can sometimes make the ninth inning interesting, but Casilla's 2.59 ERA and 25:11 K:BB ratio in 24.1 are solid, and his spot as the Giants' closer seems fairly secure.
