One of the best parts about Kyle Seager being in a career-worst slump was that nobody seemed to realize it.

Seager’s offensive numbers were still some of the Mariners’ best his manager had no idea about the downturn and even the player himself was oblivious to it all. It wasn’t until after his two-run eighth-inning homer and a solo shot in the ninth by Justin Smoak sealed a 3-1 comeback win Friday over the Texas Rangers that Seager finally grasped the extent of his slide.

“I didn’t know until the postgame interview (on television) that it was 0 for 21 so that was good to hear’’ Seager quipped with a grin. “It was one of those things where I kind of realized that I hadn’t gotten a hit in a while and it’s just one of those things that you go through. You go through the ups and downs and sometimes you can take bad swings and get hits and other times you’ll feel good and not get hits.

“For me in this case the past couple of days I’ve started to feel a little bit better.’’

The Mariners had been shut down on two hits by left-hander Derek Holland for seven innings and trailed 1-0 when Neal Cotts came on to work the eighth. That’s when Nick Franklin – in a slump of his own – drew a one-out walk. Seager followed by jacking a ball just beyond the right-field wall.

A crowd of 37596 at Rangers Ballpark looked on stunned as leaping right fielder Alex Rios failed to come up with the ball. Among those letting out a cheer in the visitors’ dugout was Mariners starter Hisashi Iwakuma (11-6).

“I was yelling ‘Get over that fence’’’ Iwakuma said through interpreter Antony Suzuki.

Yoervis Medina and Charlie Furbush got the Mariners out of an eighth-inning jam and Danny Farquhar closed out a perfect ninth after suffering his first blown save two nights before.

Iwakuma had held the Rangers to a lone run on four hits while striking out eight in his seven innings. But things looked grim with five outs to go and the Mariners on the verge of becoming the first team ever shut out three times in one season at this ballpark.

That is until Seager batting .444 lifetime at this park and riding a 12-game hitting streak here jumped on the 0-2 pitch from Cotts.

“I don’t know necessarily what the right answer is” Seager said of his hitting success here. “I mean that’s a good pitching staff so it’s not like that’s the case. I think it’s just one of those things where the couple of times we’ve come here before I’ve made a few adjustments and hopefully gotten into a little rhythm.”

Mariners interim manager Robby Thompson said he wishes all players handled slumps just like Seager.

“We knew he was struggling a little bit but I just found out he was 0 for his last 21” Thompson said. “We were just talking about it in here. You’d never know it the way that he handles and carries himself whether he’s 10 for 20 or 0 for 21. That’s the sign of a pro right there. He’s a battler and that’s why he’s in there in the third (spot).”
