The Mariners acquired first baseman/designated hitter Kendrys Morales from the Minnesota Twins on Thursday in exchange for right-handed relief pitcher Stephen Pryor. Morales, 31, is scheduled to report to the Mariners tomorrow, at which time a 25-man roster move will be made. A jersey number will be assigned to him tomorrow. Morales rejoins Seattle after a brief stint with the Twins. After signing as a free agent with Minnesota on June 8, Morales appeared in 39 games and batted .234 with 11 doubles, one home run and 18 RBIs. He had a 12-game hitting streak snapped on Wednesday when he went 0-for-4 in the Twins' 3-1 win over the Indians. In 156 games with the Mariners last season, Morales led the team in batting average (.277), hits (167), doubles (34), RBIs (80), multihit games (46) and extra-base hits (57). The 23 home runs established a club record for a switch-hitter. In 79 games at Safeco Field, he hit .282 with 21 doubles, 12 home runs and 41 RBIs.
