Does baseball need realignment and/or expansion in order to be more sound geographically & competitive?

San Antonio, Portland, San Juan, Monterrey, Oklahoma City, Sacramento, Las Vegas, and possibly Buffalo could be MLB markets in the future? One idea would be to move the D-Backs to the AL West, move the Pirates to the NL East, and move the Rangers to the NL Central. Another plan would create 8 4-team divisions with no wild card. Divisions would look like this: AL East (DET, TOR, NYY, BOS), AL Southeast (BAL, TB, MIA, WSH), AL West (POR, SEA, LAA, OAK), AL Central (CHW, CLE, MIN, KC); NL East (NYM, ATL, PHL, PIT), NL West (ARZ, SD, SFG, LAD), NL Central (STL, CHC, MIL, CIN), NL Southwest (SA, TEX, HOU, COL).
