Worried about their infield depth with Jed Lowrie absent, the Red Sox acquired utilityman Mike Aviles from the Royals for infielder Yamaico Navarro and right-hander Kendal Volz on Saturday.
Aviles, who opened the season as the Royals’ primary third baseman, has hit .286/.317/.417 in 1,148 at-bats over the last four seasons. He’s capable of playing shortstop in addition to second and third, though he’s not really an asset there. What he does do is pummel lefties: he’s hit .296/.343/.464 against them in his career.
To bring in the insurance policy, the Red Sox surrendered Navarro, a 23-year-old who took a big step forward last year to turn himself into a candidate to start in the majors. He had spent some time on Boston’s bench this year, hitting .216/.275/.351 in 37 at-bats. Much more encouraging is his .265/.356/.486 line in 181 Triple-A at-bats the last two seasons.
Still, Navarro wasn’t ever likely to crack Boston’s lineup as a starter. He may have more luck in Kansas City someday, though he will be behind Alcides Escobar at short and Mike Moustakas at third. Having picked up some outfield time this year, he may prove to be a great fit in a super-utility role.
Volz didn’t rank among Boston’s better pitching prospects. The 2009 ninth-round pick was moved to the pen at high-A Salem this year and had a 3.33 ERA and a 56/12 K/BB ratio in 51 1/3 innings.
Aviles will be arbitration eligible for the first time this winter. The Red Sox will control his rights through 2014, so not only can he help out this year, but he can step in for free-agent-to-be Marco Scutaro next year.
The Giants have acquired All-Star infielder Eduardo Nunez from the Twins in exchange for minor league pitcher Adalberto Mejia, the club announced on Thursday night.
Nunez, 29, went 0-for-4 in Thursday night’s game against the Orioles. He’s hitting .296/.325/.439 with 12 home runs, 47 RBI, 49 runs scored, and a league-best 26 stolen bases in 391 plate appearances this season. Nunez has played mostly at shortstop this season, but has also logged significant time at third base and a handful of games at second base, so he’ll give the Giants some versatility.
Nunez will likely play a lot of third base for the Giants as Matt Duffy is still sidelined with a strained left Achilles. He’s earning $1.475 million this season and will enter his third and final year of arbitration eligibility heading into 2017.
Mejia, 23, was considered the Giants’ seventh-best prospect by MLB Pipeline. He earned a promotion to Triple-A Sacramento last month after posting a 1.94 ERA with Double-A Richmond. In seven starts with Sacramento, he has a 4.20 ERA with a 43/11 K/BB ratio in 40 2/3 innings.
With a roster spot open, the Twins called up infield prospect Jorge Polanco from Triple-A Rochester, per MLB.com’s Rhett Bollinger.
Bob Nightengale of USA TODAY reports that the Mariners have received “strong” trade interest for starter Taijuan Walker. The right-hander is currently on the mend from tendinitis in his right foot. He’ll throw a bullpen on Friday at Wrigley Field with scouts in attendance.
Walker, 23, has a 3.66 ERA with an 80/18 K/BB ratio in 86 innings this season. It’s his first bit of sustained success at the major league level. What’s arguably just as intriguing is the fact that Walker will be under team control through 2020.
The Mariners have been hovering around .500 for the last month and entered Thursday six games behind the first-place Rangers in the AL West and 4.5 games out of the second AL Wild Card slot, behind three other teams as well as the two Wild Card leaders. It’s enough uncertainty which could push the Mariners to sell.
