Treinen won't be available out of the bullpen for Sunday's series finale in Pittsburgh but reported improvement after receiving anti-inflammatory medication to address tendinitis in his right elbow, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

The Athletics plan to re-evaluate Treinen when they return to Oakland on Monday, but the closer is optimistic that the medication combined with a couple days of rest will be enough for him to avoid a trip to the injured list. It's unclear whom Oakland might turn to if a save situation should arise Sunday, as setup ace Lou Trivino only recently overcame a thumb issue while pitchers with prior closing experience like Fernando Rodney and Joakim Soria have both struggled this season.

Treinen is experiencing right elbow discomfort and is set to be evaluated when the team returns to Oakland on Monday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Treinen hasn't pitched since last Sunday when he allowed four runs on five hits and two walks over 1.2 innings. It's unclear how long the elbow discomfort has been present, but it's a concerning issue for the Athletics, regardless.

Treinen (1-2) allowed four earned runs on five hits and two walks across 1.2 innings in an extra-innings loss to the Blue Jays on Sunday. He struck out one.

EDGE Analysis

Treinen's uneven April continued Sunday, with his unraveling particularly surprising considering the right-hander has been so effective over the last season-plus in a closing role. Treinen was handed a seemingly secure three-run lead to start the 11th inning. There were two men on before Treinen recorded an out, with a three-run home run and RBI single by Brandon Drury and Justin Smoak, respectively, completing the Blue Jays' comeback. While the 30-year-old sported an elite 0.68 ERA entering the outing, Treinen has uncharacteristically run into control problems thus far this season. Wednesday marked his third outing with multiple walks this season, and he's handed out 11 free passes already after issuing just 21 all of last season across 80.1 frames.

Treinen (1-1) fired a scoreless ninth inning in a win over the Rangers on Wednesday, allowing no hits, two walks and recording a strikeout.

EDGE Analysis

It took him 22 pitches due to some control problems, but Treinen was able to wiggle out trouble by getting Delino DeShields to ground into an inning-ending double play. Treinen has blown one save this season, but he's otherwise picked up where he left off in 2018 by generating an 0.68 ERA across his first 13.1 innings.

Treinen gave up one hit with one walk while striking out one in a scoreless ninth inning to record his sixth save of the season in a 2-1 win over the Astros on Wednesday.

EDGE Analysis

It wasn't the cleanest inning as Treinen allowed the potential tying and go-ahead runners to reach base, but they were stranded as the right-hander nailed down his sixth save of the season. The 30-year-old is walking too many batters with a 5.5 BB/9, but he has only allowed a run in one appearance this season and has a 0.79 ERA.

Treinen gave up a hit and struck out three in 1.1 scoreless innings to record his fifth save of the season in Friday's 8-6 win over the Rangers.

EDGE Analysis

The right-hander continues to deal. Treinen now has a 0.87 ERA and 13:6 K:BB through 10.1 innings, and as long as he gets the walks back under control, the 30-year-old should remain one of the top closers in baseball.

Treinen pitched a perfect ninth inning with two strikeouts to record his fourth save in an 8-5 victory against the Orioles on Thursday.

EDGE Analysis

This is certainly the way owners wanted Treinen to respond after blowing his first save on April 7. The 30-year-old was extremely efficient, retiring the side in 10 pitches while throwing seven strikes. He is 4-for-5 in save opportunities with a 1.00 ERA, 1.11 WHIP and 11 strikeouts in nine innings.

Treinen (0-1) allowed an earned run on two hits and four walks over 1.1 innings in a loss to the Astros on Sunday. He also recorded a strikeout and was charged with his first blown save of the season.

EDGE Analysis

The normally near-automatic closer was handed the keys in the eighth with a man on and the Astros within a run after a Tony Kemp solo home run. Treinen allowed a game-tying sacrifice fly to Alex Bregman before getting out of the frame, and he eventually issued a game-winning bases-loaded walk to Jose Altuve in the ninth after experiencing some uncharacteristic control problems. Prior to Sunday's stumble, Treinen had started the season off in trademark fashion, allowing just three hits over 6.2 scoreless frames across five appearances and notching three saves in as many opportunities.

Treinen gave up a hit and a walk while striking out two in a scoreless ninth inning Tuesday to record his third save of the season in a 1-0 win over the Red Sox.

EDGE Analysis

Xander Bogaerts nearly made things interesting with a one-out double, but he got thrown out by Ramon Laureano trying to stretch it into a triple, and Treinen took care of the rest. The right-hander has picked up where he left off last season and already has an 8:2 K:BB through 6.2 innings to go along with his spotless 0.00 ERA.

Treinen recorded a save while walking one in a scoreless ninth inning during Sunday's 2-1 win over the Angels.

EDGE Analysis

Treinen is up to 5.2 scoreless innings with two saves in 2019 after his incredible 2018 campaign. He's established himself as a top-tier closer and his job isn't going anywhere.
