Mariners 5, White Sox 4: Another late rally, another loss

The White Sox are now 0-4 on this 10-game West Coast swing, but they continue to entertain while losing.

Trailing 4-0 through six, the White Sox mashed their way into a tie with three dingers before Dan Jennings gave up a pair of singles in the ninth, the second of which was a walk-off by Guillermo Heredia.

White Sox pitching fell victim to two truths in this one.

No. 1: Dylan Covey gets killed in the fifth inning.

Covey pitched his best game yet, going six innings on just 87 pitches. Yet he gave up four runs, and three of them came after two outs in the fifth inning. Jean Segura roped a three-run shot to left, which would’ve been a startling development since Covey retired the first two of the inning on four pitches if it weren’t for the aforementioned phenomenon (the league is now hitting .538/.600/1.038 against Covey in the fifth, which is actually a slight improvement over the numbers he brought into the game). Jarrod Dyson kept the inning alive with a single and Carlos Ruiz walked before Segura went yard. Speaking of which....

No. 2: Jarrod Dyson kills the White Sox.

With a .308/.434/.440 line in 64 games, Dyson inflicted more damage against the Sox than any other team. A change of divisions didn’t change the outcome. Before he singled with two outs in the fifth to extend that inning, he cranked a solo shot of his own to give Seattle a 1-0 lead in the second.

Dyson also proved to be quite the nuisance in the ninth. He ended up on base after Jennings turned a sac bunt attempt into a forceout at second. After a cat-and-mouse game turned into a full count, Dyson took off on Carlos Ruiz’s grounder and beat Todd Frazier’s attempt to start a 5-4-3 double play, although they still got the force at first. That play mattered when Heredia singled to score Dyson and end the game.

At least the White Sox made a game of it, which didn’t appear likely while soft-tossing righty Sam Gaviglio held them to five scoreless innings. He didn’t overmatch the Sox — he only struck out two — but the Sox couldn’t barrel him up for more than a batter at a time.

Once Seattle’s bullpen entered the fray, the White Sox started hitting for power. In the seventh, Matt Davidson cut Seattle’s lead in half with a towering drive off Casey Lawrence that barely cleared the left-field wall. In the eighth, the White Sox picked up the other two runs with back-to-back homers. Todd Frazier hit a no-doubter down the left-field line, and Tim Anderson followed with his opposite-fieldest blast of his career.

Bullet points:

*Leury Garcia left the game after taking a pitch to his elbow

*The 5-6-7 part of the lineup -- Avisail Garcia, Frazier and Anderson — went 7-for-12 with a double, a triple and two homers.

*That means the rest of the lineup went 2-for-24, although one was a Yolmer Sanchez single that extended his hitting streak to nine games.
