Abad struggled on Tuesday, allowing two homers in 0.1 innings, letting a game that was 3-2 in the ninth when he entered get to 6-2 by the time he exited.

Abad has had a terrible start to 2015, currently posting a 7.36 ERA over his eleven innings. He has now allowed four homers on the years and amazingly, all four of those home runs have been by lefties. After a strong 2014 with a 1.57 ERA, Abad is quickly working himself into some low leverage situations until he can right the ship.

Abad agreed to a one-year contract with the A's on Friday, avoiding arbitration, Joe Stiglich of CSN California reports.

Abad's first season with the A's was a resounding success, as he cut his ERA from 2013 by more than half (to 1.57) and shaved more than 50 points off his WHIP. He gave up just one earned run over the final two months of the season, and will be rewarded accordingly in his first year of arbitration. However, while Abad enjoyed success against both lefties and righties last season, he likely won't be in the mix for saves while Sean Doolittle (shoulder) is out.

Abad continued his fantastic season with two scoreless innings on Wednesday against the Mets.

Abad's ERA now sits a paltry 1.62 on the season with a WHIP of only 0.80. Perhaps Abad's most impressive stat so far this year is that he has allowed exactly zero of 26 inherited runners to score this season.

Fernando Abad was ejected from Sunday's game against the Orioles for allegedly throwing at Manny Machado.

With the A's holding a 10-0 lead in the eighth inning, and Manny Machado trying to instigate trouble since the first game of the series, it doesn't take a leap of faith to believe that Abad was indeed throwing at Machado. Both benches wound up clearing after the incident, though no further trouble came from it.

Athletics acquired LHP Fernando Abad from the Nationals for OF John Wooten.

Abad was designated for assignment by the Nats last week despite posting a steady 3.35 ERA and 32/10 K/BB ratio in 37 2/3 innings this season. He should get a look for a bullpen spot next spring in A's camp.

The move was made to clear space on the team's 40-man roster. Abad had a decent 2013, posting a 3.35 ERA and 32/10 K/BB ratio over 37 2/3 innings. The 27-year-old will need to pass through waivers if the Nats hope to hold onto him.

Abad, 27, had a 1.06 ERA and 12/2 K/BB ratio in 17 innings over 17 appearances in Triple-A. The Nationals are lacking a true left-handed specialist, so there's a chance that he could stick around. However, Abad owns a 5.10 ERA in 88 appearances in the majors.

Fernando Abad was blasted for five runs -- four earned -- on six hits and three walks over just four innings in Wednesday's loss to the Pirates.

He needed 87 pitches to get through the four frames. It's fair to say the Astros' experiment with Abad in the rotation hasn't worked, as he's been drilled for 11 earned runs over just 12 1/3 frames in his first three starts. Assuming he's still in the rotation, he'll face the Cubs next week.

The 26-year-old southpaw was recently moved into the rotation in Triple-A, posting a 4.50 ERA and 9/3 K/BB in 14 innings over three starts. He shouldn't be trusted in fantasy leagues, even against a struggling Mets squad.
