Seigler started at second base, batted leadoff and went 1-for-4 with a run scored in Saturday's 5-1 win over the Mariners.
Seigler, who had been traveling with the team for its six-game road trip out west, was officially recalled from Triple-A Worcester earlier in the day and added to the starting lineup. The left-handed batter should be part of the mix at second base along with Andruw Monasterio while Isiah Kiner-Falefa (forearm) is on the 10-day injured list. This is Seigler's second stint with the Red Sox.
