Worth noting

• The Mariners became the first team since the 1970 Reds to allow three or fewer hits in their first two games of the season, giving up three hits both Monday and Tuesday to the A's. That feat has occurred just four times since 1940 in Major League Baseball.

• How good were the Mariners' first two starters? Felix Hernandez and Hisashi Iwakuma combined to go 2-0 with a 0.66 ERA, allowing just one run in 13 2/3 innings with one walk and 15 strikeouts.

• After six shutout innings Tuesday, Iwakuma's ERA since last year's All-Star break is 2.44, second-lowest of any American League starter behind the Rays' David Price (2.31).
