Jason Grilli left Monday's save appearance against the Nationals with an apparent right arm injury. It didn't look good, as Grilli threw a pitch and immediately began walking off the field. The National League's save leader yielded a walk, a home run and a double before leaving. If you're in a league where Mark Melancon is available, scoop him up now.

Jason Grilli worked a scoreless ninth inning against the Reds on Sunday, preserving a one-run lead and earning his National League-leading 30th save.

Jason Grilli worked a perfect ninth inning against the Mets on Saturday, preserving a two run lead and earning his National League leading 29th save. Impressively, Grilli needed just eight pitches to dispatch of the Mets, including a strikeout of Eric Young. The veteran right-hander has exceeded all expectations in his first season as a closer, compiling a 1.99 ERA, 0.86 WHIP and other-worldly 63/9 K/BB ratio in 40 2/3 innings.

Jason Grilli allowed a two-run homer but hung on to record his 28th save of the season in Wednesday's win over the Phillies. He got two flyouts to start the inning, but Jimmy Rollins doubled and Domonic Brown homered to cut the lead to one. Grilli then got Delmon Young swinging to end it. The Pirates' closer has struggled a bit of late, giving up six runs over his last six innings. It's worth noting that he's on pace for a career-high 78 appearances, though it's too soon to start worrying about that.

Jason Grilli bounced back from his first blown save of the year by hurling a perfect ninth inning against the Angels on Saturday. He struck out two in earning his Major League-leading 26th save (tied with Jim Johnson). The 36-year-old right-hander owns a gaudy 1.07 ERA and 0.74 WHIP to go with a 56/7 K/BB rate over 36 games.

Jason Grilli blew his first save of the year against the Reds on Wednesday, giving up a game-tying home run to Jay Bruce in the bottom of the ninth inning. As Meatloaf said, 25 out of 26 ain't bad. The homer was Grilli's first allowed this year as well, and the earned run ballooned his ERA to 0.99. Everyone is entitled to a bad pitch every now and then; Grilli will be just fine.

Jason Grilli notched his league leading 24th save in Friday's victory over the Dodgers. He allowed the first two hitters to reach on infield singles, but battled back to get the next three hitters in order, including a pair of strikeouts.

Jason Grilli tossed a scoreless ninth inning against the Cubs on Friday for his major league-leading 23rd save of the season.

Jason Grilli struck out the side to record his league-leading 21st save of the season against the Tigers on Tuesday. Now he's just showing off.

Grilli has also fanned 37 batters through 23 2/3 innings. He still has yet to blow a save this season.

Jason Grilli earned his 17th save of the season Sunday in the Pirates' 1-0 defeat of the Astros. Grilli retired all three batters he faced, needing only 10 pitches.
