Lucas Giolito has lived up to his high ceiling this season becoming an elite pitcher. He didn't pitch well in his last start. Prior to that, however, Giolito had surrendered three or fewer runs in each of his last 10 starts. The Under has cashed in seven of Giolito's last nine starts.

Boston lefty Eduardo Rodriguez is rounding into shape going seven innings in each of his last two starts. He's held opponents to two or fewer earned runs in three of his last five starts. Rodriguez is 2-0 with a 2.66 ERA in four lifetime starts against the White Sox.

The White Sox rank 24th in runs and 25th in homers. They have the second-fewest homers in the American League against lefty pitchers. Chicago isn't in great offensive form either averaging 3.8 runs in its last seven games.

Both pitchers should get a boost from the weather conditions, which call for wind blowing in at 7-8 mph.

The Under has won the past six times the two teams have played at Fenway Park.
