Burdi (elbow) successfully underwent Tommy John surgery Thursday, Daryl Van Schouwen of the Chicago Sun-Times reports.

It seems like everything about the operation went off without a hitch. Burdi will now move into the rehab phase as he eyes getting ready for the start of the 2019 season.

Treinen allowed a solo home run to Kendrys Morales in the bottom of the ninth to tie Thursday's game, blowing his fourth save of the 2017 campaign.

Treinen had been doing well recently, earning three straight holds over his last three appearances this past week. During that span, he allowed just one baserunner in 3.1 innings, while striking out four. In Thursday's affair, Treinen was called upon with two outs in the bottom of the ninth, getting Justin Smoak to pop out with one runner on. But he was unable to navigate the A's out of Toronto, blowing his second save in six appearances after coming to Oakland in a trade on July 16.

Manaea (8-5) allowed three earned runs off seven hits while striking out seven over seven innings during Thursday's no-decision against Toronto.

Besides a couple home runs to Josh Donaldson and Kendrys Morales, Manaea was able to command the strike zone yet again, marking a fourth quality start in his past five outings. This was the first time since May 20 that Manaea didn't record a single base on balls, as the left-hander was able to throw strikes on 68 of his 99 pitches. On the year, the former Indiana State Sycamore has posted an ERA of 3.82 and 1.23 WHIP with an 8.7 K/9 for the A's. He projects to face the Giants in San Francisco for his next start.

Jurado, 21, has a 4.84 ERA and 71:27 K:BB in 115.1 innings at Double-A Frisco.

Jurado has been even worse over his last 10 outings, compiling a bloated 5.84 ERA. His strikeout numbers have also taken a huge nosedive this season. All in all, Jurado has lost a bit of his prospect luster in 2017, though at just 21 years of age he still has plenty of time to right the ship.

The White Sox called up Bummer from Triple-A Charlotte on Thursday, Colleen Kane of the Chicago Tribune reports.

The 23-year-old left-hander compiled a solid 3.00 ERA in 33 innings with Double-A Birmingham, accompanied by 34 strikeouts and 16 walks. Bummer will occupy a depth role for a club suddenly lacking reliable high-leverage relievers, considering the White Sox traded David Robertson, Tommy Kahnle, Anthony Swarzak and Dan Jennings in the last week or so.

Duffey has posted a 4.63 ERA, 1.35 WHIP and 46 strikeouts in 46.2 innings in his first season as a reliever.

After coming up in the Twins' farm system as a starter, Duffey struggled in the rotation for two seasons before moving to the bullpen. Now as a reliever, Duffey has been able to pump up his velocity to 92 mph on average, and with that increase has come an improvement in strikeout rate.

Boshers has struck out 21 with an ERA of 3.86 in 25.2 innings this season.

Compared to 2016, the ERA is down from 4.25, but the peripherals suggest he's been significantly worse this season (4.59 FIP, 2.84 in 2016).

Treinen notched his fourth hold in Wednesday's 3-2 loss to the Blue Jays, allowing a hit and recording a strikeout over a scoreless eighth inning.

The 29-year-old right-hander did his job in preserving a 2-0 lead after rookie Paul Blackburn had twirled a dominant seven frames. Treinen's usage in a high-leverage scenario such as Wednesday's is telling, as manager Bob Melvin appears to be increasingly confident in the recent trade acquisition. Factoring in Wednesday's production, Treinen has given up just one unearned run on two hits over six scoreless innings since arriving in Oakland while also logging four holds.

Boxberger fired a scoreless ninth inning in Wednesday's 5-1 win over the Orioles, allowing a hit and recording two strikeouts.

Boxberger fired 11 of his 14 pitches for strikes while erasing the bad taste of his two most recent appearances -- outings in which he'd given up a combined four earned runs over two innings. The 29-year-old right-hander is likely to continue seeing plenty of eighth-inning work in games where the Rays have a lead, allowing him to serve as a bridge to closer Alex Colome. However, given that he compiled plenty of ninth-inning experience in his own right prior to this season, Boxberger could also see the occasional save opportunity in games where Colome isn't available.

Pruitt will start Friday against the Yankees, Marc Topkin of the Tampa Bay Times reports.

The 6.25 ERA he has in 31.2 major-league innings hides decent control, but a trip to hitter-friendly Yankee Stadium doesn't offer Pruitt much upside as a fantasy streamer. He'll probably leave the rotation once Jake Odorizzi (back) resurfaces from the 10-day disabled list.
