Mariners at Astros

The American League West-leading Houston Astros look to extend their winning streak to 10 games and complete a four-game sweep when they host the Seattle Mariners in the series finale on Sunday. Houston continued its torrid stretch Saturday with an 11-4 triumph in which it belted five home runs.

Jose Altuve hit a three-run shot and Collin McHugh recovered from a three-run second inning that saw him serve up three of the four blasts he surrendered to post his 11th consecutive victory. The Astros, who haven't lost since dropping a 3-2 decision at Seattle on April 22, improved to 17-7 on the season - matching the best 24-game start in franchise history (1980). Nelson Cruz swatted a pair of solo shots for the Mariners to raise his season total to a league-leading 13. The slugger, who posted career bests of 40 homers and 108 RBIs with Baltimore last year, also has driven in a major league-high 25 runs.

PITCHING MATCHUP: Mariners LH J.A. Happ (2-1, 2.30 ERA) vs. Astros RH Roberto Hernandez (1-2, 3.80)

Happ has pitched better than his record indicates, allowing fewer than three runs and working at least 6 1/3 innings in each of his four starts this season. The 32-year-old is coming off his second straight victory, a 2-1 triumph at Texas in which he yielded one run and six hits while striking out a season-high nine in 6 2/3 frames. Happ, who suffered a career-worst 15 losses for Houston in 2011, improved to 3-0 lifetime against his former team on April 22 as he limited the Astros to two runs in 7 1/3 innings.

Hernandez posted his first win of the campaign on Tuesday, allowing three runs and six hits in six innings at San Diego. The 34-year-old Dominican has deserved a better fate as he has surrendered three earned runs or fewer in each of his four outings. Hernandez is 2-5 in 10 career games (nine starts) versus Seattle despite posting a decent 3.47 ERA.

WALK-OFFS

1. Houston is three victories away from matching the longest winning streak in franchise history, which was set in 1999 and equaled five years later.
