Phillips last appeared in the majors with the Red Sox back in 2018 and will turn 41 years old later this month. The veteran second baseman played in 54 games last year for Lexington and is back for another stint this summer in the Atlantic League.

Phillips spent some time with the Red Sox last season, appearing in nine games and hitting .130/.259/.261 with one homer and a 4:7 BB:K.

The 37-year-old Phillips has played nearly his entire 17-year career as a second baseman and has never played first base. The Red Sox are using a tandem of Mitch Moreland and Steve Pearce at first, but Moreland has slumped since the All-Star break (.183 BA, .594 OPS) while battling various injuries. Phillips made a splash in his Boston debut Wednesday, when he hit a game-winning, two-run homer in the ninth inning against Atlanta.

Phillips started his tenure with the Red Sox off with a bang, taking A.J. Minter deep with two outs in the top of the ninth inning to give Boston a 9-8 lead in what was his first big-league start of the season. He also reached on a pair of walks and an error. The veteran infielder is expected to serve as a bench player for the Red Sox down the stretch, though he showed he still has a little something left in the tank.
