CHICAGO -- The A's recalled outfielder Nick Martini from Triple-A Nashville before Saturday's game against the White Sox at Guaranteed Rate Field, optioning right-hander Chris Bassitt back to Nashville.
Left-hander Danny Coulombe, who served as the 26th man for the second game of Friday's doubleheader, was also optioned to Nashville.
Bassitt started the nightcap on Friday, allowing five runs (four earned) on six hits in 5 1/3 innings. He is 0-3 this season, and he has lost nine straight decisions, dating back to 2015.

Martini, 27, was hitting .305 (68-for-223) with 38 runs, five home runs and 33 RBIs in 62 games with Nashville. He was 0-for-9 with the A's during a three-game stint earlier this month, but he recorded his first Major League hit on Saturday, a pinch-hit, go-ahead single in the eighth inning to put Oakland ahead by a run. The score held, and the A's went on to win, 7-6.
Martini had family and friends in attendance for the big moment. The only downer was that his father was away on a business trip and couldn't attend.
"Which stinks, but he's definitely someone that's gotten me to this point," Martini said. "I wish I could share it with him here, but I'm glad to get it here."
It was quite a whirlwind for Martini, who didn't learn he was being called up until late Friday night.

"I grew up a Cubs fan, but I came to a lot of games here," Martini said. "I found out late last night, and when I found out they were here, I was super excited."
Before the game, Martini said he believes he's better prepared for this opportunity.
"It definitely eases the nerves, especially since I've been here for a few at-bats, and I know most of the guys here," Martini said.
Despite Saturday's success, Martini's time in the Majors may be brief. The A's are going with a 12-man pitching staff, and Melvin said lefty reliever Ryan Buchter -- who completed a rehab stint with Nashville on Friday -- will be activated on Monday for the opener of a four-game series at Detroit.

"It'll be big," Melvin said of having Buchter back. "We've been missing that piece, that late-inning lefty that also gets righties out. That's one of the reasons we got him here, not necessarily just situationally to use him against lefties. It just makes us a better team."
For his part, Martini said he's not focused on how long he's in the Majors.
"My mindset is to just put together good at-bats, play good defense and hopefully it gets noticed," Martini said.
