Mariners minor-league report

Waldimir Balentien’s first sniff of the major leagues went so poorly earlier this season that the Mariners sent him back to Class AAA Tacoma before his confidence was too severely shaken.

It’s looking like the power-hitting outfielder is back on his game.

Balentien has been on a home-run tear, hitting four in a four-game stretch before he went hitless Monday against Tucson. Entering Tuesday, Balentien had six homers, 14 runs batted in and a .375 average in an eight-game stretch.

It won him the Pacific Coast League player-of-the-week award.

Balentien is batting .260 with 15 homers, 41 RBI and just 32 strikeouts in 173 at-bats this season with the Rainiers.

During his 32-game stint with the Mariners, he hit four home runs, including a couple of blistering shots that displayed his strength. But he also struck out 35 times in 107 at-bats, clearly showing he wasn’t ready.

The Rainiers entered Tuesday 50-52 and in third place in the PCL Pacific North Division.

Third baseman Matt Tuiasosopo had a nine-game hitting streak and catcher Rob Johnson had hit safely in eight straight.

Right-hander Oscar Villarreal pitched a scoreless inning of relief Monday, one day after he joined the Rainiers. The Houston Astros waived him on July 11.

The Rainiers will lose outfielder Mike Saunders on Sunday when the Victoria, B.C., native joins Team Canada for the Olympics in Beijing.
