Santana threw a scoreless inning while not allowing a baserunner and striking out one Tuesday against the Orioles.

Santana entered the game in the ninth inning with score tied 2-2. He retired the side in order on only 10 pitches, and he has posted a 2.35 ERA and 0.85 WHIP across 15.1 frames since being tagged for five runs by the Rockies on Aug. 1. Santana should continue to serve as Pittsburgh's closer through the end of the campaign.

Cantillo (5-3) got the win over the Royals on Tuesday after tossing eight scoreless frames while allowing just four hits and no walks. He struck out five.

Cantillo was phenomenal in what was just his third start of at least six innings pitched in his young career, and the second such start in his last two outings. Cantillo came back out for the ninth but was pulled after 92 pitches following a leadoff single by Kyle Isbel. Cantillo's velocity was notably up across the board, and he didn't issue a walk for the first time in his last seven appearances. Over his last four major-league starts, Cantillo owns a 1.09 ERA and 1.01 WHIP. He lines up for a road start against the Tigers next week.

Ashcraft allowed one earned run on two hits and two walks while striking out four across three innings Wednesday against the Orioles.

Mike Burrows drew the traditional start, but Ashcraft followed him into the game to work in bulk relief. He struggled to consistently hit the zone, with only 36 of his 63 pitches finding the strike zone. While he was inefficient, Ashcraft also racked up seven swinging strikes and recorded all three of his outs in the fifth inning via the strikeout. Ashcraft has a 2.72 ERA and 1.16 WHIP across 36.1 innings since the All-Star break, though most of those appearances have come either in bulk relief or shortened starts.

Agnos (elbow) was scheduled to throw from the slope of a mound Friday, MLB.com reports.

Agnos has been sidelined since the end of July with an elbow injury and is hoping to ramp up in time to return this season. It's unclear whether that will happen, but Agnos appears to be recovering well from the injury.

Halvorsen (elbow) has resumed throwing from 60 feet and is hoping to return from the injured list prior to the end of the season, MLB.com reports.

This marks Halvorsen's first notable progress since he was sidelined in early August with an elbow injury. He hopes to pitch in a game before the season is over, but Halvorsen is expected to be at full strength shortly after the campaign ends if he cannot return.

Fairbanks picked up the save Tuesday against the White Sox, throwing a perfect ninth inning. He did not record a strikekout.

Fairbanks snapped a streak of five consecutive outings allowing at least one hit. During that stretch, he surrendered four runs on nine hits, including three home runs, with eight strikeouts across five innings. Wednesday's save was Fairbanks' 25th of the campaign, tying his most saves in a season during his seven-year career. He has a 3.15 ERA in 54.1 innings this season.

Walker allowed a hit and a walk in a scoreless inning to earn the save in Tuesday's 5-3 win over the Diamondbacks.

Walker imploded versus the Cardinals on Saturday, and while he wasn't that sharp Tuesday, he was able to get the job done. He's converted five of six save chances over his last seven appearances, and he's been scored on in just two of 14 outings since the start of August. For the season, Walker has a 3.86 ERA, 1.18 WHIP and 55:15 K:BB through 56 innings, and he's converted 15 of 20 save opportunities.

Munoz secured the save Tuesday against the Cardinals, striking out one and allowing one hit in a scoreless ninth inning.

Munoz recorded his 34th save of the season in his third straight scoreless outing. The All-Star right-hander owns a 1.63 ERA, 1.05 WHIP and 71:25 K:BB through 55.1 innings on the campaign. Munoz is third in the major leagues in saves for the year, and he's established a strong grip on the Seattle closer role.

Pagan secured the save Tuesday against the Padres, striking out one in a clean ninth inning.

It was Pagan's first save of the month of September and his 27th of the year. The 34-year-old right-hander has been rather shaky of late -- he has a 5.02 ERA in 15 appearances since the start of August -- but he appears to still have the trust of manager Terry Francona as the team's closer. Through 60.2 innings, Pagan has a 3.26 ERA, 0.94 WHIP and 73:20 K:BB.

Jax will serve as the Rays' opening pitcher for Wednesday's game against the White Sox, Ryan Bass of FanDuel Sports Network Sun reports.

With Ryan Pepiot unavailable for his scheduled start Wednesday due to fatigue, the Rays will turn to Jax to lead off what's expected to be a bullpen game. The 30-year-old right-hander has given up eight earned runs in just 12 innings since being acquired from the Twins at the trade deadline and isn't expected to pitch past the first inning during what will be his second opening assignment in seven days.
