Santana earned the save in Wednesday's 2-1 win over the Blue Jays, striking out one in a perfect ninth inning.

Santana made quick work of the middle of Toronto's lineup, retiring the side in order to close out his ninth save in 11 chances this year. Santana has turned in five straight scoreless appearances (5.1 innings), allowing just two hits while striking out four in that span. His ERA is down to 2.32 through 54.1 innings this season with a 0.88 WHIP and 43:11 K:BB.

The Dodgers optioned Diaz to Triple-A Oklahoma City on Wednesday.

The move corresponds with the Dodgers recalling Paul Gervase from Triple-A. Diaz has struggled out of the bullpen in three of his last five outings, allowing five runs on five hits and two walks while striking out five across 4.2 innings over that span. He'll look to regain his control in Triple-A and could return to the majors should the Dodgers need right-handed depth out of the bullpen.

The Dodgers recalled Gervase from Triple-A Oklahoma City on Wednesday.

Gervase will join the Dodgers' bullpen while Alexis Diaz was optioned to Triple-A in a corresponding move. Gervase was acquired by the Dodgers from the Rays in late July and has appeared in five games for Oklahoma City, where he's posted a 2.08 ERA and 0.85 WHIP over 8.2 innings. He pitched in five major-league games for Tampa Bay before being traded and had a 4.26 ERA and 1.74 WHIP across 6.1 frames.

The Pirates optioned Shugart to Triple-A Indianapolis after Wednesday's win against the Blue Jays.

The right-hander has been a quality bullpen piece for Pittsburgh this year with a 3.50 ERA, 1.15 WHIP and 29:17 K:BB across 43.2 innings, but he'll lose his place on the big-league roster with top prospect Bubba Chandler set to be promoted. Given Shugart's performance, he should receive another look with Pittsburgh before the end of the season.

The Brewers recalled Rodriguez from Triple-A Nashville on Wednesday.

Rodriguez made one appearance for the Brewers earlier this season and surrendered three earned runs over 3.1 innings, and he's back with the big club ahead of Wednesday's game against the Cubs. He's worked out of the rotation with Nashville this year and has a 4.10 ERA, 1.41 WHIP and 70:30 K:BB across 63.2 innings.

The Padres optioned Marinaccio to Triple-A El Paso on Wednesday.

Marinaccio's latest stint in the big leagues lasted less than a week, as he had been called up from El Paso on Saturday. He made a two-inning relief appearance later that day against the Dodgers but had gone unused out of the bullpen in the Padres' last three games. Marinaccio will give up his spot on the active roster to lefty JP Sears, who was recalled ahead of his scheduled start Wednesday versus the Giants.

The Pirates optioned Sisk to Triple-A Indianapolis on Wednesday.

Acquired from the Royals at the trade deadline, Sisk initially reported to Indianapolis before the Pirates recalled him last Friday. The team wasted no time putting Sisk to work, as he made relief appearances four of the past five days and was charged with three earned runs on three hits and one walk while striking out four across 3.1 innings. He'll head back to the minors and give up his spot on the 26-man active roster to Johan Oviedo, who was recalled ahead of his scheduled start Wednesday versus the Blue Jays.

The Diamondbacks recalled Jarvis from Triple-A Reno on Wednesday.

Jarvis has made eight appearances for Arizona this season, allowing seven runs with a 13:7 K:BB over 14.1 innings. He's pitched exclusively as a starter at Reno, so Jarvis will offer some length out of the big-league bullpen.

The Diamondbacks optioned Hoffmann to Triple-A Reno on Wednesday.

Hoffmann was unscored upon in his first three appearances for the Diamondbacks but was touched up for a total of five runs across his last three outings. His spot on the 26-man active roster and in the bullpen will be absorbed by Bryce Jarvis, who was recalled from Reno.

Seymour surrendered one earned run on three hits and one walk while striking out three across three innings in Tuesday's 5-1 loss to the Padres.

Seymour worked in long relief once again, logging three innings for the fourth time in nine appearances this season. The right-hander threw 33 of his 54 pitches for strikes and recorded at least three strikeouts for the third time. He owns a 3.92 ERA, 1.40 WHIP and 16:8 K:BB, allowing six home runs in 20.2 innings.
