"Swings the bat pretty well," A's manager Bob Melvin said. "We probably have him targeted to play against some lefties. I know he's played a little bit of second, mostly third. We'll see where he fits in, but it'll probably be against left-handed pitching."
Melvin said he'll see how comfortable Valencia and Brett Lawrie are at second base in the next few days. When a lefty pitches, Eric Sogard will often be out of the lineup. Either Lawrie or Valencia will likely play second, while the other starts at third.
"I don't really foresee anything being too complicated over there," said Lawrie, who took grounders at second before batting practice on Monday. "Just make the easy one and try to play under control."
Valencia is scheduled to arrive in Oakland on Tuesday. The A's face Baltimore left-hander Wei-Yin Chen on Wednesday, so there's a chance Valencia could start as early as then.
The 30-year-old right-handed hitter has spent six seasons in the Majors, including time with the Twins, Red Sox, Orioles, Royals and Blue Jays.
Billy Butler played with Valencia in Kansas City and said A's fans can expect a versatile player with some pop in his bat.
"He's played multiple positions, so that's what our team kind of looks for," Butler said. "He was having a nice little year [in Toronto], must have just not fit into their plans over there."
• The A's reinstated switch-pitcher Pat Venditte (strained left shoulder) from the 15-day disabled list Monday and optioned him to Triple-A Nashville.
Venditte made three rehab appearances with Class A Advanced Stockton and two with Nashville, allowing two earned runs in 5 2/3 innings.
"After an injury it gives us a chance not to want to run him out there too much," Melvin said. "At the big league level, if a guy's pitching well, you're going to want to get him out there quite a bit."
