zep-CHIN-ski. That's how you pronounce the last name of reliever Marc Rzepczynski, whom the Nats acquired from the A's today in exchange for minor league infielder Max Schrock. The 30-year old southpaw joins a Washington pen whose 3.28 ERA leads the NL, but lacks lefty options with vet Oliver Perez struggling and rookie Sammy Solis sidelined (shoulder). In 56 games with Oakland, zep-CHIN-ski posted a 3.00 ERA, but his 14.2% walk rate was the highest among AL relievers (min. 30 IP).
