Casilla pitched two perfect frames Monday, picking up the win in an extra-inning game versus the Dodgers.

The Giants went with Casilla in the 11th inning of a tie game, paving the way for rookie Hunter Strickland to earn his first career save. The situation was an oddity in an extra-inning affair. Casilla is still firmly entrenched as the closer.

Casilla struck out a pair during a scoreless inning against the D-backs on Wednesday to record his 17th save of the season.

Sergio Romo tossed a scoreless eighth and was credited with a win Wednesday. As the Giants continue to push toward a playoff spot, Casilla remains in the ninth-inning role after replacing Romo in late June.

Casilla slammed the door on the Diamondbacks on Tuesday night, tossing a perfect ninth inning with one strikeout in the Giants' 2-1 win.

Casilla (16 saves, 1.86 ERA) has successfully converted 16 of 20 save opportunities, and while the Giants have recently stated he would share closing duties with Sergio Romo, he has clearly been their man when he's available.

Casilla struck out one during a scoreless ninth inning Saturday to earn his 15th save of the season.

Sergio Romo served up a solo home run in the eighth inning, and Casilla continues to handle the closer role capably for manager Bruce Bochy. As a result, he appears to be safely entrenched as the team's ninth-inning option for the stretch run.

Casilla picked up the save in Monday's make up against Colorado from a suspended game in May.

The save technically counts as his second of the season, but it pushed his total to 14 on the season. It was also his third-consecutive save since manager Bruce Bochy indicated he would split closing duties with Casilla and Sergio Romo. Romo hasn't seen a save opportunity since that statement, and he gave up the game-winning run to the Rockies in the nightcap. So it looks as if Casilla's role as the team's closer is relatively safe for now.

Casilla will share closing duties with Sergio Romo from here on out, CSNCalifornia.com reports.

Casilla picked up the save Saturday night against the Brewers, but not before making things interesting by a run on two hits and a hit by pitch. Though his numbers on the season remain sterling, Casilla has been only so-so since assuming closing duties in early July following Romo's ouster. Meanwhile, Romo has pitched dramatically better since moving to middle relief, and it appears he's regained the trust of manager Bruce Bochy. Both relievers should probably be held for now, but given Romo's proven success in the closer's role prior to this season, he should be viewed as the favorite to ultimately emerge as the victor in the job battle.

Casilla earned the save Saturday against the Brewers despite giving up two hits and a run.

That's back-to-back saves for Casilla, who is battling teammate Sergio Romo for the Giants' closer role. Romo came on in the eighth inning with two outs and struck out the only batter he faced on three pitches to earn the hold.

Casilla notched his 12th save with a scoreless ninth inning in the Giants' 4-1 win over Colorado on Thursday afternoon. He walked one in the outing.

Earlier San Francisco announced that Casilla (12 saves, 1.68 ERA) and Sergio Romo would share closing duties the rest of the way, but Romo pitched a scoreless eighth inning before Casilla came on to finish it off. Expect Romo to get an opportunity some time soon, but Casilla could still be the better bet if he stays out of trouble over his next few outings.

Casilla will share save opportunities with Sergio Romo for the rest of the season, CSN Bay Area reports.

Casilla's blown save Wednesday was his first since becoming the Giants' closer, but his 4.70 ERA over his last eight appearances is worrisome. Former closer Sergio Romo is touting a 2.08 ERA since being demoted from the closer role, so manager Bruce Bochy stated that he will use both pitchers in closing situations going forward. This obviously hurts Casilla's value in terms of seeing save opportunities.
