GAME: Brewers (49-66, 5th, NL Central, -21.5 GB) at Mariners (53-61, 3rd, AL West, -11.5 GB) GAME #: 115. SERIES: 1st of 3 games. MEETING: 1st (1st series between the teams since 2010). WHEN: Friday, 7:10 p.m., Safeco Field. STREAKS: Mariners W 1; Brewers L 1. TV: Root Sports. RADIO: ESPN 710, Mariners Radio Network

When, in May, the Mariners determined that Jesus Montero couldn’t catch (or hit, or run) they shipped the plodder to AAA Tacoma and elevated backup Kelly Shoppach to the starting role. But when, in mid-June, the Mariners figured out Shoppach couldn’t hit (.196) a lick, they designated him, promoted No. 1 pick Mike Zunino and signed 41-year-old Henry Blanco when Jesus Sucre went down.

Zunino would still be catching had he not suffered a broken hamate bone in his left hand in late July. By default, that elevated Blanco to the starter’s role. To replace Zunino, the Mariners signed another veteran backup, 34-year-old Humberto Quintero.

You don’t expect much out of a 41-year-old starting catcher and a 34-year-old backup. But Blanco started his career in Seattle with a bang June 15 when, at 41 years, 290 days, he became the oldest Mariner to hit a grand slam (vs. Oakland) and the first to do so in a Seattle debut since Leon Roberts April 9, 1978.

Quintero hit his first home run Aug. 2 in an 11-8 win at Baltimore and came back with another, and three RBIs, Wednesday in the 9-7 comeback victory over Toronto.

Blanco (3) and Quintero (2) have now combined for five home runs in 23 games, giving Seattle an unexpected power boost while Zunino recuperates.

Joe Saunders, who will start for Seattle Friday night, has yet to work with Quintero, but he’s worked three games with Blanco with less than shining results. Saunders has a 6.89 ERA in those games.

Saunders is coming off a 3-2 win at Baltimore and will face RHP Kyle Kohse, who hasn’t contested the Mariners since 2007, when he pitched for Cincinnati.

The Mariners and Brewers haven’t faced each other since 2010 when Seattle lost a three-game series at Miller Park (2-1). Before that, the teams hadn’t played since 2004, also in Milwaukee. This series marks the Brewers’ first at Safeco Field.

He has worked into the seventh inning in six of his starts.
